The cardiac subspecialty of electrophysiology (EP) diagnoses and treats arrhythmias. This includes use of pacemakers to treat bradycardia, implantable cardioverter defibrillators (ICD) for tachycardia, heart failure and patients at risk of sudden cardiac arrest, and cardiac ablation treatments to treat heart rhythm disorders.

Researchers examined decades of data from more than 5,000 patients, sharing their findings in the Journal of the American Heart Association.


While current guidelines endorse screening for people aged 65 and above, a massive simulation published in JAMA Health Forum suggests that cost-effectiveness may extend to even younger age groups.

There is not agreement among the top structural heart experts if CT is required for left atrial appendage occlusion (LAAO), but a Henry Ford Hospital study shows it can improve outcomes.

In-hospital mortality was especially high among TAVR patients presenting with hypertrophic cardiomyopathy, according to a new analysis.

The KardiaBand device from AliveCor is a more reliable tool for identifying atrial fibrillation (AFib) than the Apple Watch 4, according to a new head-to-head analysis published in JACC: Clinical Electrophysiology.

The study's authors noted that the ECG acquisition technology in these wearable devices appears to be quite effective. The automated algorithms, however, could still be improved. 

The projected number of acquired cardiomyopathy cases are expected to greatly outpace the number of new familial cardiomyopathy cases by 2031 in the U.S., driven mainly by poor lifestyles. This is expected to have a big impact on healthcare.

“Even if we compensate for the differences in population size, the U.S. is still miles ahead when it comes to total cardiomyopathy cases," explained Walter Gabriel, MPH, an epidemiologist and analyst on the report.

At TVT 2022, there was debate whether CT imaging is needed for preplanning LAA procedures, and several new devices in development were discussed.

Leadless pacemaker technology is expanding its ability to treat more patients with dual-chamber pacing.


Researchers studied data from more than three million patients, including approximately 76,000 who underwent heart surgery.

Large peridevice leaks after left atrial appendage occlusion (LAAO) are incredibly rare and not associated with a greater risk of adverse outcomes, according to new research published in JACC: Clinical Electrophysiology.[1] Smaller residual links are more common, however, and associated with a risk of thromboembolic and bleeding events.

The study's authors reviewed data from more than 50,000 patients, presenting their findings in JACC: Clinical Electrophysiology.

COVID-19 can have a serious impact effecting the heart during and after infection. The ACC released expert consensus decision pathway for the evaluation and management for the cardiovascular consequences of COVID infection and long-COVID, also known by its official clinical designation as post-acute sequelae of SARS-CoV-2 infection (PASC).

A new study reveals the damage caused to cardiovascular programs by the COVID-19 pandemic will continue to accrue unless mitigation strategies are implemented quickly. The review found a number of people dying are at home from heart conditions.
